ok here's my issue:
Opened pool to liner stain.
Chlorine reduced to 0- added Stain Free= clear liner overnight
Added 1 qt of Jacks Magic Magenta Stuff and slowly start adding chlorine (bleach)
adjusted ph with washing soda plus
now 2 days later the pool water turned a light tint of green
test readings are:
FC = 4
ph = 7.8
T/A = 70
CH = 50
CYA = 50
Temp 80 F
I did notice that the DE filter is approaching the time to backwash
Any suggestions on my next course of action?
thanks in advance.
